Hi Daniel, you can use something like the macro in the attached file, adapting
it to fit
your needs. It is not the same as a "cmake -E date" command, but it is useful.
Bye

# - Get the current date from the system
# This file defines the macro TODAY that can be used to
# retrive the current date.
#
# This is the definition of the macro
# macro TODAY(result)
#
# After retriving the current date, it set the variable ${result}
# in the format YYYYMMDD. In addition the following variables
# are also set:
# ${result}_YEAR to YYYY
# ${result}_MONTH to MM
# ${result}_DAY to DD
#
# Example:
# include(Today)
# today(CURRENT_DATE)
# message(STATUS
"${CURRENT_DATE_YEAR}-${CURRENT_DATE_MONTH}-${CURRENT_DATE_DAY}")
# will print YYYY-MM-DD.
#
macro(TODAY RESULT)

execute_process(COMMAND "date" "+%d/%m/%Y" OUTPUT_VARIABLE ${RESULT})

to '00000000'")
